This invention relates to tape controlling devices for stock quotation projecting machines.

Among the objects of the present invention it is aimed to provide for stock quotation projecting machines an improved device for controlling the tape consisting essentially in operatively connecting the ticker itself with the switch elementof an electric motor connected to drite the tape drawing means.

These and other features, capabilities and advantages of the invention will appear from the subjoined detail description of specific embodiments thereof illustrated in the accompanying drawing in which Figure 1 illustrates diagrammatically one embodiment in which the switch element is associated with the electric current of the ticker;

Fig. 2 is a side elevation of a portion of the tape a drawing means; and Fig. 3 illustrates diagrammatically a portion of another embodiment in which the switch element-is operatively connected with the presser arm of a ticker.

In the embodiment illustrated in Fig. 1, the ticker T is illustrated diagrammatically as having the several magnets l, 2, 3 and 4. The magnets 1 and 2 are connected by the conductor 5 with the connection plate 6 and by the conductor 7 with the connection plate 8. The connection plate 8 is connected by the conductor 9 with the magnets 3 and 4, and the magnets 3 and 4 are in turn connected by the conductor 10 with the connection plate 11. The connection plate 11 is connected by the conductor 12 with the outlet plug 13 representing the source of telegraphic impulses which is connected by the conductor 14 with the ticker switch 15. The connection plate 6 is connected by the conductor 16 with the ticker switch 15. The connections 11 and 6 are connected to the relay 17 by the conductors l8 and 19 respectively.

The relay 17, in the present instance, is illustrated as mounted on the bracket 20 which has an arm 21 to the upper end of which is pivotally connected the armature 22 for cooperating with the core 23 of the relay 17. The armature 22 has mounted thereon the spring contact member 24 for cooperating with the spring contact member 25 mounted on the standard 26. The contact 25 is connected to the motor 27 by the conductor 28.

' The contact 24 is connected by the conductor 29 with the outlet plug 30 which in turn is connected by the conductor 31 with the resistance 32 which is connected by the conductor 33 with the motor 2'7.

The motor 27 has fixed on its shaft 34 the pulley 35 which is connected by the belt 36 with the pulley 37 which is fixed to the shaft 38 journaled in the housing 39. The shaft 38 has formed thereon. the worm 40 which meshes with 80 the worm wheel 41 fixed on the shaft 42 on which are fixed the pulleys 43 and 44. The pulley 44 is connected by the belt 45 with the pulley 46 fixed A on the shaft 47 journaled in the bearing 48 formed at the end of the arm 49 extending from the housing 39. The shaft 47 also has fixed thereon the drawing tape roller 50 which is caused to be engaged with the tape by the idler roller 52, see Fig. 2, journaled in the upper end of the bracket 53 which is pivotally connected at 54 to the arm 49. Such bracket 53 has secured thereto a pin 55 on which is slidably mounted a'weight 56 similar to the construction illustrated in the co-pending application Serial No. 253,302 of James W. Decker.

The pulley 43 is connected by the spring belt 57 to the pulley 58 which is fixed on the end of the shaft 59 journaled in the bearing 60 formed at the end of the arm 61 extending from the housing 39. On the shaft 59, there is fixedly mounted the rewind reel 62' which receives the so tape 51 after it passes the drawing roller 50.

From the foregoing it will be seen that an electric impulse is transmitted to the relay 1'? at the time a message is transmitted by the ticker, when an electric impulse is caused to pass through the 5 ticker T. In the transmission of a message, these electric impulses will succeed one another in rapid succession. A single electric impulse would cause the relay 17 to be energized to attract the armature 22, in turn to cause the contact 24 to engage the contact 25, thereby permitting the current from the outlet plug 30 to pass through the motor 2'7 and excite the motor, to in turn drive the tape drawing roller 50 and rewind reel 62.

It is believed that when a message is transmitted to the ticker, the electric impulses for transmitting such message wilLso rapidly succeed one another that after the armature 22 has once been attracted by the relay 17, it will re v main so attracted and at any rate sufiiciently de pressed, and cause thecontact 24 to engage the contact 25 until the end of the message has been reached, and that the mere fact that the electric impulses when succeeding one another will cause momentary interruptions in the transmission of the current to the relay 17 will not cause interruptions of suflicient duration to permit the armature 22 to be released before the next succeeding electric impulse has been transmitted. 11

However, to insure the engagement ofthe contact 24 with the contact 25 from the of the message until the completion of the same,

' there is provided in the present instance a retardthe passage 67 which extends up to the upper end of the cylinder 66 to afford communication between the lower end of the cylinder and the upper end of the cylinder. The piston 65 is provided with a passage 68 extending therethrough and'provided with a check valve 69 at its lower end to permit the ready discharge of the oil through the passage 68 from the upper end of the cylinder 66 into the lower end of the cylinder 66, but to obstruct the passage of the oii through such passage 68 from the lower end of the cylinder up into the upper end of the cylinder.

In view of the foregoing, it will be seen that the oil in the cylinder 66 cooperates with the piston 65 to form a dash pot or retarding device whereby the piston 65 can quickly rise, to cause the armature 22 to descend and in turn to cause the contact 24 to engage the contact 25 when an electric impulse is transmitted to the relay 17, but that in the succeeding interruption, the plug 65 and cylinder 66 will cooperate to retard the descent of the arm 63 and the rise of the armature 22. To cause the arm 63 to descend upon the cessation of current transmission to the relay 17, there is provided the spring 69 for exercising a downward tension on the arm 63. When the message has finally been completed, and no further current is transmitted to the relay 17, the tension of the spring 69 will be sufficientjgradually to cause the arm 63 to descend during which action the oil in the lower end of the cylinder 66 will be caused to pass through the passage 67 up into the upper end of the cylinder 66. In order to control the velocity of the passage of the oil through the passage 67, the adjusting screw 70 is provided. Preferably means such as the adjusting nut 71' are provided to adjust the tension in the spring 69.

In the embodiment partly illustrated in Fig. 3, the part of the mechanism above the line oa illustrates another means for transmitting to the relay 17, electric impulses resulting from the transmission of a message to the ticker.

In this embodiment there is illustrated the magnet 71 of a ticker which is connected by means of the conductor 72 with the ticker switch 73, which ticker switch 73 is connected by the conductor 74 with the outlet plug 75, and which outlet plug 75 in turn is connected to the magnet 71 by the conductor 76. There is also illustrated the presser arm 77 of a ticker which is actuated by the magnet 71, that is caused to be attracted with each electric impulse transmitted. The presser arm 77 is provided with the usual spring 78 for exercising a tension against the action of the magnet 71 to withdraw the presser arm 77 from the magnet 71 upon the cessation of an electric impulse. In the present instance, the presser arm 77 has connected thereto a bracket 78 which is insulated therefrom and which is provided with a. contact member 79 to cooperate with the contact blades 80 and 81 respectively, which are mounted on the insulated block 82. The contact blade 80 is connected by the conductor 83 with the outlet plug 84, which outlet plug 84 is connected by the conductor 18, see Fig. 1, with the relay 17. The contact blade 81 is connected by the conductor 19, see Fig. 1, with the relay 17, the mechanism below the line a-a of Fig. 3 being identical with the mechanism below the line aa of Fig. 1 and is therefore not illustrated.

It is obvious that various changes and modifications may be made to the details of construction without departing from the general spirit of the invention as set forth in the appended claims.
